7(v+8)=-5(3v-8)+4v eching

$$7 ( v + 8 ) = - 5 ( 3 v - 8 ) + 4 v$$

v uchun yechish

$$v=-\frac{8}{9}\approx -0,888888889$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

7 ga v+8 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$7v+56=-5\left(3v-8\right)+4v$$

-5 ga 3v-8 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$7v+56=-15v+40+4v$$

-11v ni olish uchun -15v va 4v ni birlashtirish.

$$7v+56=-11v+40$$

11v ni ikki tarafga qo’shing.

$$7v+56+11v=40$$

18v ni olish uchun 7v va 11v ni birlashtirish.

$$18v+56=40$$

Ikkala tarafdan 56 ni ayirish.

$$18v=40-56$$

-16 olish uchun 40 dan 56 ni ayirish.

$$18v=-16$$

Ikki tarafini 18 ga bo‘ling.

$$v=\frac{-16}{18}$$

\frac{-16}{18} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$v=-\frac{8}{9}$$
